Description

Technical Field

[0001] The utility model belongs to the technical field of rectifying devices, and particularly relates to a flue gas rectifying device. Background Technique

[0002] The application of trays in desulfurization towers is an effective improvement method. By increasing the gas-liquid contact area, trays can improve the desulfurization efficiency and reduce the investment and operation costs of equipment. In the field of wet desulfurization, trays are used to increase gas-liquid contact and are generally arranged at the lowest or the second lowest layer of the equipment. Trays in desulfurization towers need to withstand the corrosion and erosion of slurry, so the materials used are generally anti-corrosion and wear-resistant alloys.

[0003] The application of trays in the limestone-gypsum desulfurization process has the following advantages: evenly distributing flue gas: the evenly distributed holes on the trays are beneficial to the uniform distribution of flue gas in the tower and can play a role in combing the flue gas flow field in the tower.

[0004] For example, a wet desulfurization efficiency improvement device disclosed in the utility model patent with the patent application number 202122828796.8, the structure setting of its tray can effectively reduce the operation resistance of the desulfurization absorption tower and increase the mass transfer efficiency of wet desulfurization.

[0005] Common trays are fixed by welding, which is extremely inconvenient in the later replacement process and requires cutting first. For this reason, the utility model patent with the patent application number 202321819072.X discloses a detachable tray and a desulfurization tower; its detachable connection method between the tray body and the annular support can solve the problems of inconvenient replacement operation and low replacement efficiency of the existing trays in the desulfurization tower. However, its detachable fixing method has the defect of unstable fixation. Summary of the Utility Model

[0009] A fixed pressing strip is provided between each sieve plate, and the fixed pressing strip is detachably connected to the support beam frame; both sides of the upper end of the fixed pressing strip have inclined surfaces. When the fixed pressing strip is connected to the support beam frame, it can press the adjacent sieve plates on both sides and push them to move; clamping edges are provided on both sides of the support beam frame, and the first sieve plate can be clamped at the corresponding clamping edges;

[0010] A number of clamping plates are fixed on the support beam frame, wedge-shaped openings are provided on the clamping plates, and corresponding rectangular through grooves are provided on the fixed pressing strip.

Specific embodiments

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] As Figure 1-8 shown, a flue gas rectifying device includes a support beam frame 1 and a tray 2; the tray 2 is composed of a plurality of sieve hole plates 200 arranged in sequence; each sieve hole plate 200 is inserted into the support beam frame 1, and a convex edge 201 is provided at the bottom of the sieve hole plate 200, and a corresponding slot 100 is provided on the support beam frame 1, and the convex edge 201 can be inserted into the corresponding slot 100. A plurality of sieve holes 2000 are provided on each sieve hole plate 200.

[0031] A fixed pressing strip 3 is provided between the sieve hole plates 200, and the fixed pressing strip 3 is detachably connected to the support beam frame 1. Clamping edges 101 are provided on both sides of the support beam frame 1, and the first sieve hole plate 200 can be clamped at the corresponding clamping edge 101.

[0032] During installation, first insert the convex edge 201 of the first sieve plate 200 into the corresponding slot 100, and then push the first sieve plate 200 respectively to make it snap into the corresponding clamping edge 101. After that, load the other sieve plates 200 in sequence. After the other sieve plates 200 are installed, the convex edges 201 on adjacent sieve plates 200 are located in the same slot 100. Finally, install the fixing strip 3 between each sieve plate 200, that is, squeeze the two convex edges 201 located in the slot 100. During the installation of the fixing strip 3, since the two sides of its upper end have inclined surfaces 300, it can press down the adjacent sieve plates 200 on both sides and push each sieve plate 200 to move through the inclined surfaces 300 (the slot 100 has a certain width to ensure that the convex edge 201 can move therein).

[0033] The fixing strip 3 can be detachably connected to the support beam frame 1 by means of bolts or the like. However, since it is located inside the desulfurization tower, after long-term operation, the bolts will be corroded, affecting disassembly. Therefore, the following detachable connection method is preferably adopted for this device:

[0034] A number of clamping plates 4 are fixed in the slot 100 of the support beam frame 1. The clamping plates 4 are provided with wedge-shaped openings 400, and the fixing strip 3 is provided with corresponding rectangular through grooves 301. During installation, insert the fixing strip 3 between adjacent sieve plates 200, and the clamping plates 4 pass through the rectangular through grooves 301 and protrude. Then, by knocking one side of the fixing strip 3, the fixing strip 3 moves, and the upper surface of the fixing strip 3 gradually cooperates with the wedge-shaped opening 400 to achieve clamping, and the fixing strip 3 presses down to clamp the adjacent sieve plates 200 on both sides and pushes each sieve plate 200 to move through the inclined surfaces 300. During disassembly, by knocking the other side of the fixing strip 3, it moves in the reverse direction, the fixing strip 3 is not clamped at the wedge-shaped opening 400, and finally the fixing strip 3 is lifted and removed.

[0035] Furthermore, in order to facilitate knocking, raised knocking parts 302 are provided at both ends of the fixing strip 3. The cross-sectional shape of the fixing strip 3 can specifically be a T shape.

[0036] Furthermore, the support beam frame 1 includes a ring beam 102, cross beams 103 and longitudinal beams 104. A number of cross beams 103 and longitudinal beams 104 are provided. The number of cross beams 103 is fixedly connected to the longitudinal beams 104 to form a grid shape; both ends of each cross beam 103 and longitudinal beam 104 are fixedly connected to the inner side of the ring beam 102. The support beam is fixed inside the desulfurization tower, and the ring beam 102, cross beams 103 and longitudinal beams 104 can be fixed by welding.

[0037] Furthermore, the cross-sectional shapes of both the cross beam 103 and the longitudinal beam 104 are concave shapes. The longitudinal beam 104 adopts a complete integral structure, and its concave structure can form the slot 100.

[0038] Further, a plurality of water permeable through holes 105 are provided on the support beam frame 1, and the water permeable through holes 105 are specifically arranged in the slots 100; liquid can flow into the slots 100 through the gaps between adjacent sieve plates 200 and the fixing bars 3, and finally be discharged through the water permeable through holes 105.

[0039] Further, the sieve holes 2000 on the sieve plate 200 can be in the shape of round holes commonly used in the prior art, or can be in the shape of gears in a wet desulfurization efficiency improvement device disclosed in the utility model patent with the patent application number 202122828796.8 (as Figure 9 shown).

[0040] Only the preferred embodiments of the present utility model have been described in detail above, but the present utility model is not limited to the above embodiments.
